ill be placing them above for easy browsing ^^ i think the categories on the side is not that catchy..
ill only place five buttons, for more categories just check the right column of the page
for brands check the side, its below the categories
for specific search pls type what your looking for on the search box :)
i just used "insert jump break" recently, was not able to use it for my past posts, they might look long even your browsing by categories or my home page.
